Preparing Commercial Plumbing Systems for Tenant Turnover
Commercial tenant turnover can cost property owners up to 30–40% of a unit’s annual lease value. While changeovers are a natural part of managing commercial properties, you can mitigate many of the associated costs with a proactive approach—especially when it comes to plumbing.
The time between tenants is ideal for maintenance, and plumbing systems should be a top priority. Tackling inspections and repairs now can help prevent bigger issues later—and set the stage for a smooth move-in process for your next occupant.
If plumbing systems aren’t properly checked before a new tenant arrives, you risk costly repairs, delays, and tenant dissatisfaction. Here’s how to prepare your building’s plumbing systems for turnover and avoid those headaches.
Why Plumbing Maintenance Matters During Tenant Turnover
No two tenants use a space exactly the same. Over time, usage patterns can cause uneven wear and tear on a building’s plumbing infrastructure. Between tenants is the best time to evaluate system performance and make necessary adjustments.
Preventative maintenance during these gaps can help you:
- Prevent plumbing emergencies
- Minimize incoming tenant complaints
- Maintain health and safety compliance
- Protect the long-term value of your property
Working with an experienced commercial plumbing partner means you can handle maintenance quickly and efficiently—without delaying occupancy timelines.
Tenant Turnover Plumbing Maintenance Checklist
What should you inspect and address during tenant turnover? Below are some key tasks to keep top of mind.
Inspect for Leaks and Visible Damage
Begin with a thorough walkthrough of the vacated space and its surrounding plumbing lines. Check under sinks, around toilets, near water heaters, and behind access panels for any signs of leaks or corrosion.
Don’t overlook ceilings and walls—especially in multi-story buildings where plumbing issues can affect more than one unit. A professional plumbing team equipped with a moisture meter can also detect leaks hidden behind drywall or under flooring.
Test the Water Pressure
Inconsistent water pressure can indicate deeper issues, such as sediment buildup, leaks, or worn-out valves. During turnover, be sure to:
- Measure water pressure at key fixtures
- Check flow consistency across sinks, toilets, and appliances
- Note any slow drains or irregular flows
This ensures your incoming tenants won’t run into water performance issues—especially critical for businesses with high water usage like kitchens, salons, or medical offices.
Clear Drains and Check for Blockages
Even if everything appears to be working fine, a buildup in the drain lines may be lurking out of sight. Some tenants are more mindful of plumbing systems than others, and you never know what was washed down sinks or drains. A qualified commercial plumber can clear out:
- Sink and floor drains
- Tub or shower lines
- Main drain lines exiting the unit
It’s always better to catch a clog before it turns into a backup—especially once a new tenant is up and running. Hire a commercial plumbing company that can clear your drain with a mechanical snake or a hydro jet. They can clear out sink and floor drains, tub or shower lines, or main drain lines exiting the unit.
Check and Operate Shut-Off Valves
Every commercial unit should have clearly marked shut-off valves for water supply lines. However, if they haven’t been used in years, valves can seize, corrode, or leak. During tenant turnover, test each valve to:
- Confirm it opens and closes properly
- Check for corrosion or leaks
- Replace any worn or malfunctioning components
You also need to educate new tenants on the location of these valves. If there is a leak or other plumbing emergency, they can shut off the water flow until the issue can be fixed.
Sanitize and Flush All Fixtures
If the plumbing hasn’t been used in a while, flush water through all fixtures to clear stagnant water and prevent bacteria buildup. This is especially important if the space will be used for food preparation or healthcare services.
A licensed plumber can also treat water lines if needed for specialty use cases or regulatory compliance.
Inspect Water Heaters
Water heaters are often out of sight and out of mind. During tenant turnover, they need attention. Check the following:
- Leaks or rust around the tank
- Faulty temperature and pressure relief valves
- Burner or heating element condition
If your system has water pressure boosted or recirculation pumps, verify that these components are functioning properly.
Verify Compliance
Even minor modifications—such as relocating a sink or updating fixtures—can create new plumbing codes or accessibility requirements. During turnover, it’s smart to confirm that the system still complies with local codes and regulations.
An experienced commercial plumber can help identify and address these issues upfront, avoiding surprises during inspections or occupancy approvals.
